摘要：
The single-photon ionization of the ground state of a helium-like multicharged ion, which is accompanied by a simultaneous excitation of the residual ion to the np states, is studied using nonrelativistic pertubation theory with respect to the electron-electron interaction. Formulas describing the cross section for the process being studied are obtained. These formulas exhibit a scaling behavior in the target-nucleus charge number Z and in the principal quantum number n. Numerical calculations are performed for nonrelativistic energies including the near-threshold region.
